This is a few shots of a heat sink I modified and constructed from a standard AM2 heat sink block.
I could not find any standard blocks for an AM2 64 Duel 6000+ for sale on their own so I decided to experiment to make my own, after having Purchased a scythe ninja revision B and it wouldn't fit in my full tower ATX case.

This first shot is of all the component parts before assembly.
The part that makes contact with the CPU was fashioned by hand using 3mm Thick Copper plate, as was the top plate to mount top cooler on.all cooling fins are made from 1mm copper plate.




The next shot shows part way through assembly. The 5 copper tubes you can see go right the way through the block and are soldered to a copper CPU plate which atatches to the base of the block with countersunk grub screws as you will see in the photo a bit further down





This next shot shows the complete assembled unit. You can see the copper base plate as mentioned in the last photo which the copper pipes are atatched to.




This is another shot taken from a different angle. Here you can see the grub screws that hold it to the standard heat sink block.




Here is a shot of the finished and sprayed product




We decided to test this on an AM2 64 Duel 3800+ chip in an Asrock Alive Sata2 Glan board.
Overall we did not see any dramatic cooling using this home made device but, one really good thing it did was hold it's temperature a lot more constantly than the standard 3800's heat sink and fan.

We enabled the CPU boost in the bios and it droped 1 degree and held its temp even when under full benchmark using Everest. I will be testing on my AMD 6000 x2 cpu and will let you know the results when ive tested it.

By this do you mean it was at a consistantly high temperature? I'm sorry to sound negative but the thing just looks wrong to me and if it was me and I found that a scythe ninja didn't fit my case my first thought would probably be, "lets find a proper heat pipe sink which does fit my case and buy that instead"

Also, as far as I can tell from looking at what you have done you would have been better off using solid copper bars if anything. Hollow tubes are doing nothing if they don't have the heat pipe wick inside them. Also, since it looks like you've sealed both ends of these tubes you've got yourself some little pressure vessels which depending on how hot the air gets inside you might get little pop sometime which might make you jump a bit.

Wouldnt have filled them as it would be difficult to get the fluids for them.

Most heatpipes simply use water, but the pressure inside is lower than atmospheric which decreases the boiling point. In a desktop case you wouldn't need a wick as gravity would facilitate the return of the working fluid to the hot end of the heatpipe, however in a tower case the heatpipe would be horizontal so would require a wick.

Since you aren't going the heatpipe route I am completely baffled by the use of copper tubes? As Bubo points out, you'd be far better off with solid copper bars rather than hollow ones. Because the cross sectional area is far smaller there will be much more resistance to conduction in a hollow tube than a solid cylinder.
 
Well, ignoring all of the negative posts above (what is with some people?! :confused: ), I say well done for getting off your backside and trying to do something interesting!!

It sounds like you had a bit of fun, and you're obviously quite proud of what you did, hence the post!

It's very easy to go to a shop and buy the latest and greatest cooler, but I think that's missing the point!

Thanks for sharing, and I look forward to Mk2!! :)
 
Its certainly an interesting idea... but im sticking with my Amanda!
It also appears that the OP has been quite affected by some neg critiscm as he has has not yet reposted, still on one post!

To be fair, there actually aren't any really negative posts that I can see, most people have given feedback on his project which is all you can expect after posting something like this, isn't feedback essential in projects? I think a lot of useful stuff has been said here to help him out if he decides to try again !!

Nice effort, I love seeing homemade stuff like this !!

Shame the OP hasn't posted again though :(
 
I'd be interested to see the exact temps he is getting, definitely a first that i have seen, especially being confident enough with it to use on quite an expensive (relatively) piece of kit.
